Technical Data | Electromechanical Cylinders EMC

Technical Data and Dimensions EMCSizes 32 to 100 follow the standard cylinder series according to ISO 15552.

Built-in ball screw drives have a diameter of 12 mm to 40 mm.

The EMC size is selected according to:

– Thrust – Stroke – Linear speed

The actual values must be smaller than the maximum permissible values.

Excess travel

Excess travelEffective stroke

EMC length

Maximum travel smax

smax = maximum travel (mm)

For safe operation, the excess travel must be longer than the braking distance. The acceleration travel can be taken as a guideline value for the braking distance.In most cases, this will be sufficient: Excess travel = 2 · screw lead (P)Example: Ball screw (d0 x P) 12 x 5: Excess travel = 2 · 5 mm = 10 mm

Maximum travel distance smax per customer specifications (minimum 100 mm)

Maximum travel = effective stroke + 2 · excess travel

EMC with Motor Mount and Coupling

ᎅ When an EMC is ordered with motor mount, motor and foot mounting, this will be delivered pre- assembled. If the foot mounting is to be retrofitted to the cylinder end cap, the motor mount has to be removed first.

For more information, see “Mounting Instructions for EMC,” R320103103

The motor mount serves to fasten the motor to the EMC and acts as a closed housing for the coupling. The coupling transmits the motor drive torque free of distortive stresses to the EMC’s ball screw journal.

EMC with Belt Side DriveThis configuration of the EMC results in the shortest possible installation length. The compact, closed housing protects the belt, secures the motor and serves as a base for fastening mounting elements.

The following gear ratios are available:i = 1 : 1i = 1 : 1.5i = 1 : 2

The timing belt side drive can be mounted in three different directions (RV01 to RV03).

Mounting elements are attached at the rear end of the belt drive. The screws are included in the delivery of the mounting elements. Before attaching the mounting elements, remove the set screws from the timing belt side drive.
